| Abstract;Computer-generated hologram (CGH) is made for three dimensional image reconstruction of a virtual object. Error diffusion method is used to improve the reconstructed image. The selection of diffusion coefficient exerts an influence to the image quality of the reconstructed image. Therefore, many researchers study the optimization of coefficients. Genetic algorithm (GA) and neutral network (NN) are known as effective optimization of coefficients. In this article, estimation of coefficients using statistical analysis is done. Using regression analysis, it's possible to relation between coefficients and object position. Image quality of reconstructed by the method is worth than by using GA. But, the quality is better than former method. And processing time is very short differing from GA and NN. This paper presents the suggested method and the reconstructed image. (author abst.) |
